SPECIFICATION forming part of Letters PatentNo. 706,601, dated. August 12, 1902. Application liled August 26,1901.. l Serial No; 73,315. (No model.)

To a/ZZ whom it may concern:

Be it known that I, JOHN EMERSON SCOTT, acitizen oftheUnitedStates,residingatPhila delphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Punching- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to effected herein with expedition and facility.'-

It guards against liability of splitting the last `from pressure or force exerted or delivered thereon through the spindle,as when the work" is hammered upon the last. It provides for the insertion of the thimble or lining into thelast previous to the punching or striking up the odsets or lips upon said thimble or lining and in continuation of said operation for such punching up of said lips or offsets, forcing said lips or offsets into the walls of the spindle-socket. Simultaneously with such penetration the fibers of the wood thus displaced will result in the formation of shoulders opposing said offsets or lips to eect the interlocking of the thimble and shoe-last to hold the thimble against accidental or premature withdrawal from the last. It also provides for simplicity of construction of the parts and the consequent manufacture of the same at a minimum cost, duc.

'Ihe nature of the invention consists, generically stated, of a plunger or carrier adapted to be suitably mechanically operated and having a cutter or punch adapted to be separately actuated to punch or strike np the lip Or offset in the `thimble or lining into which said plunger is inserted for the action of said 5o punch or cutter.

It further consists of the particular means for the actuation of said parts as connected tion and arrangement of parts, substantially i Vas hereinafter more fully disclosed, and specitically pointed out by the claims.

InV the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a side elevation thereof with the4 complex lever for actuating both the thimble or tube carrier or plunger and the cutteior punch elevated. Fig. 2 is a plan view of the same. Fig. 3 is also a side view showing said lever depressed as in punching vor cutting up the lips or offsets upon the thimble or lining. Fig. it is a longitudinal section taken on the line ma: of Fig. 1, extending through said lever. Fig. 5 is a vertical section taken on the lineg/ y of Fig. 1. Fig. 6 is a horizontal section taken on the line sa of Fig. 1. Fig. 7 is a vertical section taken through Fig. 1, extending through said lever and the plunger and punch or cutter. Fig. 8 is av section taken on the line w w of Fig. l. Fig..9 is a broken detailed section showing more particularly the punch,the interior of the plunger containing the same, and the point of connection between said punch and its actuating-lever. Fig. 10 is a horizontal section taken on the line a a of Fig. 1. Fig. 11 is a cross-section taken on the line l) b of Fig. 1. Fig. 12 is a broken enlarged detailed view showing more particularly the detent-actuating spring and the nger-Iever and sliding handpiece connection, with the punch, dac., actuating lever arranged in said handle.

Latitude is allowed herein as to details, as they may be changed or varied at will without departing from the spirit of myinvention and the same yet remain intact and be protected.

In carrying out my invention I provide, primarily, a suitable stand or support 1, which may for lightness be castor produced in skeleton form, with an arcuate or quadrant-like upper forward edge 1', preferably faced with a correspondingly-shaped wearing plate or surfacel", the purpose of which will appear presently. A hand-lever 2 has its inner end pivoted, as at 2X, between the outer bifurcated or forked end of an arm 2, also additionally bifurcated or forked at itsinner end and having the branches 2b thereof thus formed pivoted to the stand or support 1 near its upper IoO - as will more fully appear hereinafter.

y of the ends of the pivot of the dog 5.

versely through apertures or holes in which,

outside of said branches, are inserted split keys 4a. Said keys are preferably of a spring metal to permit the compression of their limbs in inserting thesarne through the transverse holes of said pivot-pin and vsaid limbs to spring apart after such insertion to automatically secure said pins. Said arm 2 has upward-extending parallel projections 2c, one formed with each branch of its outer bifurcated end, to and between which projections, at their upper ends, is pi-voted, as at 5b, a dog 5, carrying at its inner end a pivoted concaved shoe 5, having a preferably roughened or serrated face and opposed to the arcuate upper forward edge or quadrant l of the stand l. The forward or outer end of the dog 5 is curved or concaved upon its under surface and projects some distance beyond its pivotal connection with the upward-extending projections 2c of the arm 2at and is adapted to limit the downward movement of the hand-lever 2 in effecting the depression of the plunger and the punching operation, The lever 2 also has at its point of pivotal connection with the arm 2a an yupstanding projection 6, interposed between thesimilar projections 2b of said arm and preferablyequipped with a frictional roll or bearing 6a, adapted -to engage thelower concaved surface of the dog 5. The upstanding projections 2l of the arm 2a as the lever 2 is raised after previous depression carries the dog 5, with the shoe 52, upward between the parallel resilient or spring arms 7a of akeeper 7, suitably secured .or bolted to the upper inner end of the stand 1, as in effecting the suspension of said parts in an elevated position. Said spring-arms have theirin ner surfaces, from the outer ends inward a short distance,charnfered or beveled, as at 7X, to permit the upper edge of the projection 2c to readily engage and force apart saidY arms .for the passage therebetween of saidprojections and other parts. Said beveled surfaces themselves have formed therein similar shallow recesses 7 XX for" the passage Said spring-armshaveintheirupperedges,near the outer ends, preferably semicircular notches or seats 7b, beveled upon their inner lower edges, as at7, primarily to receive the projecting ends of the pivot 5b of the dog 5, and thus permit of such suspension or upholding of said parts in their elevated posithe plunger, as presently more fully disclosed.

The beveled surfaces or edges 7c of said seats or notches permit the pivot ends to readily 4enter said notches 0r seats 7 b, while said pivot ends seat themselves in said notches as the resilient arms 7a of the keeper 7 spring toward the projections 2c of the pivoted arm 2a, thus arresting further movement of the aforesaid parts and automatically securing the same in position.

A tubular stock or barrel 8 is screwed or held in a sleeve or collar 8a, having an inward or rearward extending lug or projection 8h, pivotally or flexiblysupported in position by parallel bars or links 8C, connected or pivoted, preferably as shown, to said lug and the stand near its inner edge. The lug or projection 8b is equipped upon its underside with a cushion of leather or like material 8X, having lateral upward-extended portions held, preferably, by'screws to the sides of said lug to prevent the marring or impairing by contact with said lug or projection of the shoelast held thereunder in the punching operation. Said collar or sleeve is also pivotally or flexibly suspended from the pivoted arm 2a by additional bars or links 8f, pivoted or connected, preferably as shown, to said lever and collar. Said collar or sleeve has preferably in one side a vertical elongated slot SXX, and through said slot is inserted a holding-screw 8d, having, preferably, a tapered inner end and engaging a screw-threaded opening in the stock o1' barrel 8. barrel has its upper forward or outer edge beveled or sloping downward and forward, as at S, to permit a limited play of the parts independently of each other. The stock or barrel 8 has suitably secured concentrically thereto within its lower end a pendent plunger or carrier 9, having a vertical slot 9a, with its bottom surface inclined downward and forward or outward, as at 9b, the purpose of which will be apparent presently;

The punch or cutter l0 comprises a shank slightly flared upward, with an inclined offset or shoulder l0at at the upper rear edge of said flare and a preferably pyramdal point or punch proper, 10b, at the extreme lower forward edge of the side of said shank. The tapered or effective oblique edge of said point or punch faces or is presented upward,` While the apex thereof projects outward or forward in the horizontal central plane of said point. Said punch has at its extreme lower rear edge a downward and forward sloping or beveled edge, as at l0, conforming to the corresponding beveled or sloping bottom of the slot in the plunger, to aid in the outward or lateral movement or deflection of said punch. j The cutter or punch l0 is pivotally hung or suspended, with its offset 10a near the point ofY suspension, at its upper end in a downwardfacing slot ll in the lower end of a preferably cylindric link or plunger 12, also pivotally hung in a downward-facing elongated slotl2, formed in the inner or inclosed end of the lever2. Thelinkorplungerl2,nearitspivotiug, point, is laterally sloped or beveled, as at 12", forward and downward from a flat upper end portion, giving a limited independent play Said stock or IOO IIO

between the parts, as necessary in the working of the device.

The lever 2 is equipped with opposite detents or pawls 13, preferably in the form of offset bars, suitably confined in position and sliding in angular grooves or channels 13a, provided leaterally in said lever. Said detents have their distant ends let into and suitably fixed to a handpiece or handle 2X by a screw or rivet, as shown particularly in Fig. 12, said handpiece orhandle also receiving the distant end of the lever 2. Said handpiece or handle, preferably in halves or sections held together by transverse -screws or rivets, among them the above-referred-to screw or rivet, as shown, is adapted to slide upon said lever 2, having internal shoulders or stops 2M), abutting the end of said lever, as shown. The halves or sections of said handpiece orhandle have around the rst-referredto rivets opposite bosses 20e, received by elongated recesses or notches 2dd in the edges of the lever 2 to permit and limit the sliding movement of said handpiece or handle upon said lever, as required in actuating the detent-s or pawls 13. A spring 29e, peferably coiled or slipped upon cylindric end portions of the detents or pawls 13 and having one end suitably connected to one of said detents and its other end connected to the end of the lever, provides for the automatic inward movement of the detents or pawls, as presently seen.

A finger-lever 14 is suitably pivoted upon the handpiece or handle 2 and has an inner toothed end engaging a notch 14X in the edge of the lever 2, by suitably actuating which the handpiece or handle 2X is moved outward, carrying with it the detents or pawls, thus permitting their disengagement from the notches of the arm 2"L and the movement of the lever 2 independent of said arms for the purpose above noted. The release of said finger-lever permits the automatic inward movement of the detents when the lever 2 is alined with the arm 2a, and consequently like rengagement of said detents with the notches 131L in the outer end of the arm 2, for the purpose before disclosed. In the forward edges of the branches of the outer bifurcated end of the pivoted arm 2L are notches 14a,

adapted to receive the inner odset ends of the detents or pawls 13.

The base of the `stand 1 may be supplied with a piece of leather, as 15, or other suitable soft material to serve as means to prevent the marring or impairment of the last placed in position for the insertion of the thimble or lining in the spindle-socket therein.

In operation the hand-lever 2 being elevated and locked in position the thimble or lining is slipped upon the plunger or carrier and the shoe-last then brought into position to permit the insertion of said thimble into the spindle-socket therein. The lever 2 is forced downward by hand. With this movement of said lever the spring or resilient arms 7 of the keeper 7 will be spread apart, thereby releasing the projecting ends of the pivot of the dog 5 from their seats or notches in said spring-arms, permitting the continued descent of the pivoted arm 2", with the dog 5 and its attached shoe, and saidhand-lever forcing the thimble or lining well into said socket of the shoe-last. Also during said movement of parts the dog 5, with its shoe or brake, will likewise be carried downward and said shoe caused to approach the arcuate portion or quandrant of the stand 1. The frictional roll of the upstanding projection of said hand-lever at the same time will engage the concaved surface or face of said dog and thus cause said shoe or brake to bind upon said quadrant, and thus hold the pivoted arm, with its adjunctive parts, atthat point, or againstfurther downward movement. In this depressed position of said parts the fingerlever 14 is actuated, having the edect to disengage the detents from the notches in the outer end of the pivoted arm 2a. The handlever 2 is thus rendered free to be moved independently of said pivoted arm farther downward. Such further movement of said handlever causes the punch or cutter l0 to be depressed into the plunger or carrier, its rear sloped edge passing down the inclined or sloping bottom surface of the slot in said plunger or carrier, directing said punch at its effective pointed end laterally outward through said slot, engaging and punching up the thimble or lining with a lip or odset. Said lip or odset will of course be simultaneously forced into the wood of the shoe'last. By the displace- `ment of the fibers of the wood thus produced a shoulder or abutment will be formed opposite to said lip or offsetfthus effecting the interlocking of said thimble or lining and the shoelast. In moving upward the lever 2 upon its pivot the finger-lever 14 is simultaneously actuated, edecting the rengagement of the detents or pawls with the notches of the pivoted arm, thus locking said arm and the lever together, permitting by continued upward movement of said lever the return of the parts to their elevated position for a repetition of the aforesaid operation thereof.

It is here observed that the machine is also adapted to operate upon tubes of any length without a closed end, as in the present instance, and punch up the same with a lip or lips. It is also noted herein that while it is stated, as above disclosed, that the punching up of the lip or offset from the thimble is effected simultaneously or continuously with the forcing or thrusting said lip or odset into the wood of the last, yet it will be understood that my machine is adapted for eifecting such forcing of said lip or odset into the wood of the last without regard to the time of punching up such lip or offset from the thimble, also that when the machine is thus used the cutting edge of the punch is omitted and such edge made of sufficient width or extent as shall be commensurate with the IOC IIC

'cross-sectional area of the inner diameter of the thimble'to properly effect such forcing out of the lip, especially when said lip or offset initially protrudes interior-ly of the thimble.
